When you complete underwater welding, a manual metal arc is used for welding. In Coffer dam welding, the welding work is done in a dry steel structure that is sealed against the structure that is to be welded. Hyperbaric welding uses a gas filled chamber that is fitted against the structure to be welded. Companies that  specialize in underwater construction conduct their own qualification tests to select the best talent. Before you apply for job, prepare yourself and practice your skill set.
